| titleOfInvention | SiO (silicon dioxide)xPreparation method of-G/PAA-PANI/Cu composite material |
| abstract | The invention relates to SiO x The preparation method of the-G/PAA-PANI/Cu composite material comprises the following steps: (a) performing ball milling treatment on the SiO; (b) carrying out heat treatment on graphite; (c) mixing the treated SiO and graphite, and performing ball milling in inert gas atmosphere to obtain SiO x -a G complex; (d) dissolving polyacrylic acid in an alkali solution, then adding the SiOx-G compound, and performing ultrasonic stirring to obtain a first mixed solution; (e) adding an aniline monomer and a cross-linking agent into the first mixed solution, and carrying out polymerization reaction under the ice bath condition; and then adding a copper acetate monohydrate solution for mixing, aging, dialyzing and drying. Copper ions are selected for doping, a synergistic effect is generated with polyacrylic acid and polyaniline, the conductivity is improved, and meanwhile, a stable SEI film is formed, so that the electrochemical performance of the prepared silicon-based negative electrode material of the lithium battery is remarkably improved. |
